Abstract

The invention provides an oil-driven coaxial six-rotor unmanned aerial vehicle transmission structure. The transmission structure comprises a first-level transmission mechanism, a second-level transmission mechanism and a third-level transmission mechanism which are connected in sequence, wherein the first-level transmission mechanism comprises a first bearing bracket, a reduction gear is arrangedin the middle of the first bearing bracket, and the reduction gear meshes with an engine gear; the second-level transmission mechanism comprises four first-level bevel gears, the four first-level bevel gears are connected end to end in a square section mode, one of the four first-level bevel gears is connected with the reduction gear, and the other three first-level bevel gears are connected withtransmission shafts respectively; the third-level transmission mechanism comprises power output assemblies, one end of each of the three power output assemblies is connected with the corresponding transmission shaft, the other ends of the power output assemblies are provided with second-level bevel gears respectively, and each second-level bevel gear is connected with two opposite third-level bevel gears in a T-shaped section mode, wherein the two third-level bevel gears are connected with rotors respectively. The oil-driven coaxial six-rotor unmanned aerial vehicle transmission structure hasthe advantages of being simple in structure, high in transmission efficiency, smooth in transmission and stable in transmission ratio.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to an oil-powered coaxial six-rotor unmanned aerial vehicle transmission mechanism. Background technique [0002] A multi-rotor UAV is a special unmanned helicopter with three or more rotor shafts. It is rotated by an electric motor on each shaft to drive the rotor, thereby generating thrust. The collective pitch of the rotors is fixed, not variable like normal helicopters. By changing the relative rotational speed between different rotors, the size of the single-axis propulsion can be changed, thereby controlling the trajectory of the aircraft. Existing multi-rotor drones are basically four-point distribution, or six-point distribution, and rarely three-point distribution. For oil-powered coaxial multi-rotor aircraft, the upper and lower rotors turn in opposite directions, so the power transmission is complicated. [0003] Patent a power-transmissio...
